copy with ssh with port other than 22

Question

How do I copy files from my local to some remote server which hosts ssh on port other than default (22).

I usually connect to the server using

ssh username@remotehost.com -p 2000

Now I need to copy files with scp

user@localbox:~$ scp ~/.ssh/id_rsa.pub user@remotebox.remotedomain.tld:~/.ssh/id_rsa_localbox.pub -p 2000

But this does not work.

Answer

scp --help or man scp would have told you the option was -P port. You also need to declare this before the file arguments:

scp -P 2000 ~/.ssh/id_rsa.pub user@remotebox.remotedomain.tld:~/.ssh/id_rsa_localbox.pub

I also wouldn't trust ~-relative links. Use full paths if you can.

But if you're copying IDs, ssh-copy-id also has an option to provide SSH connection options:

ssh-copy-id -i ~/.ssh/id_rsa.pub '-p 2000 user@remotebox.remotedomain.tld'
